SECTION 8

FINS Communications

This section provides information on communicating on EtherNet/IP Systems and interconnected networks using FINS
commands. The information provided in the section deals only with FINS communications in reference to EtherNet/IP
Units or built-in EtherNet/IP ports.

FINS commands issued from a PLC are sent via the SEND(090), RECV(098), and CMND(490) instructions programmed
into the user ladder-diagram program. Although an outline of these instructions is provided in this section, refer to the CS/
CJ-series Programmable Controllers Programming Manual (W340) for further details on programming these instructions.
